About the Brooklyn D139
D139 Prescription Glasses
There is something friendly and approachable about a round frame. The D139 is a unisex full-rim round frame, sized 51-19-140, in Crystal Grey or Crystal. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Brooklyn collection.
Crystal Grey or Crystal: which one is you?
Crystal Grey. Crystal Grey is a good everyday shade. Because light passes through it, the frame looks lighter on the face and lets your features do the talking.
Crystal. In Crystal, the frame is crystal grey. It keeps the look soft and understated, and it works especially well on fair skin.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
The details
Round frames soften angular features, so they are a great match for square and heart-shaped faces. A crystal front looks modern and light, and it goes with everything.
Whether it is your main pair or a spare, the D139 is easy to live with.
Styling tips
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
Size and fit
| Brand | Brooklyn |
|---|---|
| Colours | Crystal Grey, Crystal |
| Frame size | 51-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 44 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the D139
Your optometrist’s prescription will usually tell you which of these you need:
- Progressive lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
At 44mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots of room. Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
Made for you in our UK lab
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your D139 and sends the finished pair to you in Australia.
Keep them looking new
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
FAQs
Can I get progressive lenses in the D139?
Yes. The 44mm lens depth gives progressive lenses enough height for all three vision zones.
Is the D139 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
What size is it?
It is size 51-19-140: 51mm lens width, 19mm bridge and 140mm arms, a medium fit.
What does crystal mean?
A clear, see-through finish.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
